Glass bottles and containers are collected and taken to a glass recycling plant. There, contaminants are removed through various processes like magnets, sorting, and crushing. This recycled glass known as "cullet" is then shipped to various industries and used to make new products. Cullet can be used to make fiberglass insulation, road paint beads, countertops, dishes, and other items. It is a valuable material that saves energy and resources when recycled compared to using newly manufactured glass.
